Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to health clothing, and more specifically, it stimulates acupoints of the human body by the action of a weak magnetic force to reduce subjective symptoms such as stiffness and pain, or arthritis, low back pain, and lower back. The present invention relates to health clothing using magnetic fibers for treating leg pain diseases and the like.

[0002]

2. Description of the Related Art Various types of health clothing utilizing magnetic force have been proposed. For example, as a health garment in which several granular permanent magnets are partially attached to the part that hits the acupoint of the human body, a magnetic supporter (Japanese Patent Laid-Open No. 4-279176), a magnetic shirt (Basic and Clinical, Vol. 21, p. 5893, 1987) ), Magnetic bedding (Basic and Clinical, 23, 5593, 1989). All of these health clothing items have medium to high magnetic force (about 600
The purpose is to stimulate the acupoints and affected areas by the action of ~ 2000 gauss) to reduce shoulder stiffness, neck and back stiffness and pain, and to treat them.

On the other hand, various magnetic fibers have been proposed for application to various uses such as health clothing and filter materials. For example, one in which an adhesive layer in which magnetic powder is kneaded is simply provided on the surface of a yarn (Japanese Patent Laid-Open No. 53-111118), rubber or synthetic resin is mixed with hard magnetic fine powder, spun, knitted, and magnetized. (JP-A-55-30453), a thermoplastic polymer obtained by uniformly mixing magnetic fine powder as a core component, and a thermoplastic polymer having a softening point or melting point lower than that by 10 ° C. or more as a sheath component. Having a core-sheath structure (Japanese Patent Laid-Open No. 3-130
No. 413), or the regenerated cellulose containing 30 to 95% by weight of the magnetic fine powder previously proposed by the applicant (Japanese Patent Laid-Open No. Hei 3)
-199407 gazette) etc., the structure is various.

Recently, with the advent of superconducting magnets and the use of large-current technology, adverse effects of high magnetic fields on the human body, such as blood flow inhibition and carcinogenicity, have been taken up as new problems. Therefore, for example, in a linear motor car, the magnetic field environment inside (the passenger seat and the driver's seat) is suppressed to a weak magnetic force (10 to 20 gauss) in consideration of the effect of a long time high magnetic force on the human body.

By the way, since the health garment in which a few granular permanent magnets are partially attached as described above uses a permanent magnet having a medium to high Gauss of about 600 to 2000 Gauss,
Considering the adverse effects of the high magnetic field on the human body, there is a great concern that some side effects will occur. In addition, in the above-mentioned health clothing, since the magnet only partially contacts the acupoint of the human body, a good fit is not obtained, and the probability of the magnet accurately hitting the acupuncture point is very low, and the therapeutic effect is difficult to appear. Furthermore, since the granular magnets are held directly on the bedding, supporters, shirts, etc. by adhesion, encapsulation, embedding, etc., the feeling is bad, and the feeling that the magnets are in contact with the skin is squeezed, lumpy, and cold. There was a problem of giving an unpleasant feeling.

[0006] Further, although health garments using various kinds of magnetic fibers can solve the above-mentioned drawbacks of health garments equipped with permanent magnets, these health garments take into consideration the adverse effect of the magnetic field on the human body. No health clothes using magnetic fibers having a weak magnetic force have not been proposed yet.

The above-mentioned magnetic fiber proposed by the present applicant (Japanese Patent Laid-Open No. 3-199407) has a magnetic force of about 20 gauss.
The fiber was wound 50 times on a plate with a width of 5 cm so that the fibers did not overlap, then wound 10 times on top of this, magnetized with a general-purpose magnetizing device power supply, and the surface magnetic flux density was measured. That is, the magnetic force in the state of clothing in the present invention is completely different in dimension.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of such a situation as described above, and is safe without side effects even when worn or used for a long time, and has a good fit and wind feeling. Along with this, it is a technical subject to provide health clothing that uses magnetic fibers whose magnetic force accurately acts on the acupoints of the human body.

[0009]

The inventors of the present invention have made extensive studies to solve the above-mentioned problems, and as a result, have found that a low magnetic force, particularly 5
~ 50 gauss magnetic force beneficially acts on the human body, and
There are no side effects, and especially when a magnetic cellulosic fiber is used as the magnetic fiber, the resulting high hygroscopicity, high moisturizing property, good feeling, fit, drapeability, and a synergistic effect of the above effects can be applied to the human body. The present invention has been reached by finding that the usefulness of the is further improved.

That is, the present invention has the following configuration. (1) A clothing using magnetic fibers as at least a part thereof, wherein the surface magnetic flux density has a weak magnetic force of 5 to 50 Gauss, which is a health clothing using magnetic fibers. (2) The health clothing according to (1) above, wherein the magnetic fiber is a magnetic cellulosic fiber.

The surface magnetic flux density in the present invention is measured by a Gauss meter GM-1225 type (manufactured by Denshi Kogaku Kogyo KK).

The present invention will be described in detail below. The healthy clothing of the present invention includes various supporters such as the shoulder supporters shown in FIGS. 1 and 2, clothing such as corsets, arm covers, shirts, socks, and underwear, as well as bedding such as blankets, duvets and mattresses. If it uses a magnetic fiber as its constituent material, the form is woven,
It may be knitted or non-woven, and the tissue is not particularly limited.

The health garment of the present invention may be composed of 100% magnetic fibers, but in order to improve the texture and tear strength, it is interwoven with non-magnetic materials such as polyester, nylon, acrylic, polyurethane, cotton and rayon. It is preferable to use a cloth obtained by performing knitting or the like. Further, a twisted yarn of magnetic fibers and these non-magnetic materials may be used.

The magnetic fiber which constitutes at least a part of the health garment of the present invention is a hard magnetic fine powder having a particle size of 5 μm or less, more specifically, an alloy system such as Alnico or Fe—Cr—Co, Ba,
30 to 95 parts by weight of various magnetic fine powders of oxides such as Sr, Pb ferrite and magnetite and rare earths such as rare earth Co and Nd-Fe-B in 100 parts by weight of polymer constituting the fibers It means that it is contained at a ratio of parts, and may be either long fibers or short fibers.

The material of the magnetic fiber is polyester,
Synthetic fibers such as nylon and cellulosic fibers may be used, but cellulosic fibers that are excellent in flexibility, hygroscopicity and moisture retention are preferable. As cellulosic fibers, viscose method, cuprammonium method, solvent spinning What was obtained by the method etc. can be used.

The health clothing of the present invention has a weak magnetic force of which the surface magnetic flux density on the surface in contact with the human body is 5 to 50 gauss, preferably 10 to 30 gauss, but this value is an arbitrary unit in the health clothing. It shows the magnetic force with respect to the surface area (m ² ).

Magnetization may be performed in any state of yarn, cloth and clothing, but the surface magnetic flux density of 5 to 50 is obtained in the state of clothing.
In order to make Gauss, it is preferable to apply it to the entire surface in the state of cloth or clothing.

In order to impart a weak magnetic force with a surface magnetic flux density of 5 to 50 gauss to the health clothing, the magnetizing condition, that is, the charging voltage at the power source of the magnetizing device is adjusted according to the mixing ratio of the magnetic fibers in the health clothing. It is necessary to magnetize it.

That is, the magnetic fiber has an upper limit of saturation magnetization that can be magnetized, and this depends on the type and content of the magnetic fine powder contained in the magnetic fiber. In addition, since the magnetic force of the health garment varies depending on the weaving structure, the knitting structure, and the mixing ratio of the magnetic fibers, the charging voltage at the magnetizing device power supply is adjusted according to the mixing ratio of the magnetic fibers in the healthy clothes. It is necessary to magnetize so that the surface magnetic flux density is 5 to 50 Gauss.

[0020]

In the present invention, the surface magnetic flux density of the health clothing is set to a weak magnetic force of 5 to 50 gauss, and the reason for this is not clear, but health using conventional medium to high magnetic force (about 600 to 2000 gauss) is used. It is possible to promote blood circulation to the human body and stimulate the affected area from a side different from clothing, which reduces various symptoms such as stiff shoulders, arthritis, back pain, and lower back and leg pain diseases. Can be achieved.

When magnetic cellulose fibers are used as the magnetic fibers, the cellulose fibers are highly hygroscopic, highly moisturizing and have a good feeling, fit, and drape, which are easy to adapt to human skin and are gentle. The combination of the characteristics and the effect of the low magnetic force described above can further reduce the symptoms.

(Wearing Effect of Shoulder Supporter) The wearing effect of the obtained shoulder supporter was confirmed by conducting a clinical test under the conditions described below. [Clinical test conditions] Subjects: 25 patients with stiff shoulders as the main symptom were randomly selected. Shoulder supporter wear period: November 1992 to 1993 2
Month (about 3 months) Wearing method of shoulder supporter: As shown in FIG. 2, the shoulder supporter was worn such that the magnetized surface of the shoulder supporter was in direct contact with the skin of the subject. Shoulder supporter should be worn all day, and it is prohibited to administer other magnetic applicators, napkins, or other therapeutic devices that affect the efficacy of this test product or other physical therapy.

The wearing effect of the shoulder supporter was evaluated by comparing the subjective symptoms of shoulder stiffness of the subject before and after administration of the shoulder supporter. The criteria for subjective symptoms were as shown in Table 1, and the degree of improvement in subjective symptoms was calculated by the following formula. (Amount of improvement in subjective symptoms) = (Judgment score after wearing shoulder supporters)-(Judgment score before wearing shoulder supporters) In cases where the degree of improvement in subjective symptoms is +1 or more, the effect of wearing shoulder supporters is " Yes, it was determined.

[0028]

[Table 1]

The results of the clinical test on wearing the shoulder supporter are shown in Table 2.

[0030]

In addition, there were no cases of complaining of side effects such as abnormalities on the skin, discomfort or pressure when wearing the shoulder supporter.

[0032]

EFFECTS OF THE INVENTION According to the present invention, the surface magnetic flux density of health clothing is set to a weak magnetic force of 5 to 50 gauss, and various symptoms occurring in the human body, such as stiff shoulders, arthritis, back pain, and lower back and leg pain diseases, etc. In contrast, conventional granular medium to high magnetic force (about 600
It is possible to obtain an improvement effect that could not be obtained with health clothing that has several permanent magnets with up to 2000 gauss) attached, and because of the low magnetic force, there is no concern about side effects.

When magnetic cellulose fibers are used as the magnetic fibers, the high hygroscopicity, high moisture retention and good feeling, fit and drape properties of the cellulose fibers are synergistic with the above-mentioned effect of low magnetic force. Depending on the effect, it becomes possible to further improve the effect of reducing various symptoms.
